1995 GMC JIMMY WHILE DRIVING ENGINE DIED I HAD TE FP CHANGED FUEL FILTER NEW COMPUTER NEW PLUGS WIRE D CAP COIL AT THIS TIME NO GAS NO START

check for spark, no spark, no fire engine wont run, possible bad ignition coil, wire from coil to distributor cap, no power to ignition coil from ignition switch (rare) wire broken to ignition coil (even rarer)

Ive had a few of those ,,have someone check ,,ur coil packs,,they go bad ,,make em skip and drink gas ,,and u want even no,,,usally the problem with those,,,good luck

Hi, Ok you have confirmed that it's not a fuel problem. You need to check for spark. Pull the coil wire off of the coil(secondary lead-looks like a spark plug wire) Have some one crank it over and listen for a popping sound. IF yes, spark is at the coil, that means all ignition sensors are working. Next check for spark at ends of wires after cap. IF no replace cap and rotor. IF yes remove a couple spark plugs and check for fouling(wet, fuel etc...) IF yes replace or clean plugs and retest for starting. IF no spark is present at coil you need to scan computer and watch for rpm signal. IF no rpm signal, replace crankshaft sensor with OEM delco part. BIGGEST problem with these engines is Cap and Rotor burn out.

Have you checked your fuel pressure. You may have a bad fuel pump. If you have good fuel pressure take a good look at your cap and rotor. 4.3 liters have a notorious cap and rotor problem along with a coil wire issue. The coil wire can rub on the firewall or other places and cause you problems. I would start with checking your fuel pressure with a fuel pressure gauge.

Maybe timing belt broke?

My 92 Subaru would not start. New rotor, cap, replaced fuel filter. No gas getting to filter. When gas trickled in carb, runs like a top. I think the fuel pump out.

I had a problem just like that on my blazer and it turned out to be the wire harness on the fuel injectors. It could also be your fuel injectors, had to replce mine at 85000

Just a thought, have you checked yout TPS(throttle position sensor)? I had similar problems with my 89 GMC Jimmy 4.3l, however a code 44 is strange. Also check to see if your problems go away if you advance the timing a few degree's.

Hope this helps
