Hi. My 1993 Jimmy died at an intersection today. It had been running a little rough recently, but had no trouble starting. After several failed attempts to start it, I replaced the cap, coil and plugs, but I still don't seem to be getting any spark. Any ideas?

The automatic choke could be faulty and stay on or could be blocked filter

do you have a check engine light on if so need to get it scanned they scan them for free at your local autopart store need code

i have seen many strange things happen with the distrib cabs on these

There are a number of sensors and controls that can cause this problem (mainly MAF, TPS, IAC motor, EGR valve, O2 sensor) and you will have to figure out which one (or more) is causing the problem. First check for error codes with an OBDI code checker and follow up on the results.

I had the same problem mechanic couldn't figure it out turned out to be the egnition shuting off

Basically clean up before use like opening the plugs and adjusting the spark gaps, spray some carb cleaner at the intake & if The soud of the engine smoothens even slightly, then add some it to the fuel in the fuel filter & gun the engine a few time. Flush the radiator and fill in frsh coolant/water. Check the level of water in the battery and top up with distilled water. Clean the air filter and check fan belt tightness. After these small maintenace checks it should run OK.......sodeep

First thing you can do to try a simple fix is replace each spark plug, check each plug for signs of fuel/air mixture

if your plug is black is rich, if ur plug is white is lean.

in this case repost your findings. in the mean time if they look golden or light brown, replace them and make sure they are gapped to ur level of psi you are running.

you can find the gap specs for how much boost you are running on most DSM websites or by searching.

Try to unplug the mass airflow sensor and start it. It will idle higher but should run fine. If it works then you need a MAF sensor. Be sure you have an OBDII code puller to clear the computer when done

Sounds like the head gaskets are leaking.

I have a 1993 toyota camry , when it start it , it runs for about 2minutes and shuts off,can u help me with that problem.
