no spark/hott coilpack

[pearl91chevy]

alright, took the truck out last night for the first time since last summer.. just went to get gas and started my way back.. suddenly it started chugging real bad, and i mean really bad. first wasnt to bad, went to 2nd and i couldnt drive it at all, kinda felt like i would be flooring it and letting off quickly and 3rd almost the same.. got a lil bit farther and truck completely died, tried starting it and nothing.. 2 times it started and as soon as i would take off it would die.. i managed to get it pulled home and checking stuff out.. now when i turn the key on, i can hear the ignition coilpack making wierd noises and it gets real hott, and btw the motor is getting no spark.. what should i be looking for right now?

x2 on the module

[pearl91chevy]

the ignition control module is whats inside the distributor correct? i went to orileys and thats what they told me to pull out and have them test, and its out now so im gonna check it in the morning.. now what is the Electronic Spark Control Module? i brought it in and they couldnt find anything on the computers.. Would this have something to do with my problem? Also suddenly no gas is coming through the injectors, fuel pump is priming, fuel is in the tank, and injectors are getting power, also new fuel pump.. hope something has to do with that...

and just curious about what these plugs might go or do..
under middle of dash:


Pretty much passenger side:


on ecm:

[nolowis2low]

okay give me all the info you agve them at youre orillys and ill go to mine and see what i cant find, but what did the test on the module show? and on the escm iam not positive but i think these are on distributorless ignition systems. and on the fuel problem, new filter, could be the regulator is stuck closed.

what kind of engine are we dealing with?

[pearl91chevy]

im about to leave right now to get the module tested.. info i think u mean by motor correct? 91 s10 2 wheel drive 2.8L.. i stuck a 3.1L motor in but still used my intake manifold/accesories off the 2.8L so that wont make a diffrence..

[pearl91chevy]

well it failed all 3 time at orileys, took it to autozone just to be safe and it failed all 3 times there to, they said its completely dead.. so i just bought a new one with lifetime warrenty.. would would cause this to go bad? just old age since its original? i did put a msd coil on before i made the trip to the gas station so could this have been the problem? im putting the original coil back on to be safe..

[pearl91chevy]

so ya.. swapped that modual and still no spark.. now what? o and btw im getting gas again.. im so confused

[nolowis2low]

yea fail three times and its deff no good, i frogot to tell tou to make shure they test it three times and they fail like any electrical device. but did they tap on it while testing, this HAS to be done to get an accurate test. and please tell me you got a Borg warner. i had a Master Pro and with an Accel and an MSD Coil the Master Pro module just burned up, either get BWD or Accel modules.

couple other things to check make shure the rotor button is seccure and in right, make shure all of the probes on the cap are good. and check the coil wire to make shure its still good and intact

[pearl91chevy]

alright when back out and checked the plugs running to the coilpack.. checked with a test light, the light color plug had power on one wire.. the other dark plug had nothing on either wire.. should there be power to it?
one im holding has no power, before the plug on the wire, and at the end of the plug..

[pearl91chevy]

so after messing around more, i ran back to orileys to test that new modual to see if it fried again but its still good after 3 test.. they said i coulda maybe jumped timing and to check rotor to see if it spins smoothly when cranking which it does.. they said its more then likely the coilpack..

[nolowis2low]

if it is and you dont want to spend much ive still got my stock one if you want to try it out.....

[pearl91chevy]

im gonna plug everything back up again today and see if anything new happens first.. when i had my original coilpack in, i drove it around the block numberous times a few weeks ago and didnt have a single problem, power was there and it was smooth.. i installed that msd the day it lost spark, so im worried it somehow fried the ecm.. but ill let ya kno in a bit man thanks!

[nolowis2low]

you cant fry the ecm with a coil pack all it does is amplify the voltage to the plugs, nothing is feeding to the ECM, but if the ignition control module cant handle it it will just say fock you and take a shit.

[pearl91chevy]

so my ecm should be fine then? thats my biggest concern considering there 90 bucks..

[nolowis2low]

should have no problems with the ECM, but did you ever find anything with that plug??

[pearl91chevy]

well good news.. just went down and took my time putting it all back together.. made sure all plugs were tight and i cranked it over, and it started right the hell up, gave it some gas and reve'd it and its fine, i cant believe it.. so im airin up the tank now then gonna go around the block a few times before i take it on another trip lol ill be back in a few to let u kno how it goes

[nolowis2low]

sweet deal might just of had somthin crossed

[pearl91chevy]

well i took it for a drive for a good 15 min and didnt have a single problem.. had good power like i did last summer, no hesitations or stumbles.. thanks for the help!! ill send a message your way if i have any more problems.. thanks again so much!!

[nolowis2low]

no problems dude, so did you use the stock coil pack or the MSD

[anotherbaggeds10]

wow deja vu. im having exactly the same problem right now with my 2.8. i changed my fuel pump sending unit and filter all at the same time. now the pump turns on, the relay clicks it starts until it gets warm then took a shit and wouldnt start again. i let it sit for a while and it would start then take a shit. im wondering if that is the same thing thats wrong with mine? ill have to pull it and have it checked

[anotherbaggeds10]

yeah the module passed for me, back to the drawing board

[pearl91chevy]

i just used the original coilpack.. i didnt want to take a chance frying something out again ya know? idk what happened about the fuel thing but its working fine.. i just gotta replace a brake line and ill be out driving it again hopefully..

[nolowis2low]

vacume lines?

[pearl91chevy]

went and drove it around town for a good hour today.. having problems with either battery or alternator.. had to push start it today poppin the clutch.. took the battery in and it was dead completely which makes me wonder if my alternator took a shit..

[nolowis2low]

yea it could have taken a shit cause my alt went out goin to work(oreillys) and it killed my battery, but both were the original one from the factory.

[pearl91chevy]

well my alternator is original but the battery is a red top.. also remember how i said it was buckin real bad in 2nd gear.. well ya its doin that again horribly.. im hoping its just no power from the battery so im not on a goose hunt trying to figure out the problem.. i have the battery on a charge over night so ill see what happens in the morning and ill prob have that alt. tested while im at it..

[nolowis2low]

well amn if the battery ends up bad and its not underwarrenty get the oreilly brand of the yellow top, its about 150, but its a damn good battery and a longer warrenty.

[TCossuto]

okay im not reading all that postage so I'll break down your no fire issue:

Duh your not going to get your injectors pulsing if your distributer does not trigger for spark.

Get a remand' distributer. New ignition module and pickup sensor.

[ABMBlazer]

i was wondering is there any relays that involve the ignition in any way?

[TCossuto]

realys for ignition? like the fuel pump relay? Becides that, no.

[pearl91chevy]

alternator and battery tested good every test.. battery was at 20% so they charged it to 100% and was fine for a full day of driving.. then got to the point it would start even trying to push and pop the clutch.. i had to get it jumped.. dunno wat the prob is besides my compressor for the bags could be pullin to many amps but dunno how considering i didnt have a single problem with this last year..
