93 jimmy no start

sexytruck21 · 06-23-2008, 09:53 PM

my buddy has got a 93 jimmy 4x4 that wont start. it cranks and cranks but wont fire. the truck was running fine (as fine as it could i guess) on the way to work when it just died, at 75 mph on the freeway just shut off. Still have power in dash lights etc. the fuel pump was replaced a lil over a month ago and fuel filter last week. cap and rotor done right before fuel pump. I have no idea where to go next. please help. with gas the way it is and me losing my car pooling buddy i need it to run.

did it run out of gas? is it getting gas? spark?

sexytruck21 · 06-23-2008, 10:06 PM

spark for sure its about 60 miles into a full tank and its getting gas but still have yet to test fuel pressure. i depressed the test valve with a small screw driver while cranking and got a 2 inch high burst and that was it.

pull some plugs n see whats up with em..

Possible pickup coil. Did you actually test for spark at the plug? Mine did the exact same thing and that was what it turned out to be.

i checked for spark off the distributer wire, will check plugs and wires prolly just replace im not buying parts will get back to you.

I've even seen the plug come off the coil and cause the same problem!

ok heres the update, now i really need help. Bought fuel pressure guage and found i have 58-60psi. changed plugs, wires, cap and rotor. nothing happened. tryed starting fluid truck fired for a few seconds and nothing. so now im stuck and have no clue where to look next. I'm thinking injectors or pcm. thanks again much appreciated.

Well if it tried to run after starting fluid and you have 50-60#s of pressure, I would guess you have a non-functioning spider injector.

same exact thing happened to me a month ago. did everything you did. found out it was the ignition control module. try replacing that. then my 89 started right up.

When you check for spark, you need to see continuous spark, not just one spark.
