Then my guess would be fuel pressure regulator. Or a wiring problem.

1990chevy suburban 2500 350 died while driving and won't restart I can hear the fuel pump turn on I have changed the fuel filter and still nothing what's next


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)

Won't start fuel pump replaced new tank and relay have fuel after fuel filter runs if I put fuel down throttle body. this is on a4,3.


Nephew had similar problem on different vehicle - had spark to plugs, limited gas, everthing else checked. I did one thing first - check for two fuel filters - one in the tank was only screens and one in the line itself. Found a little in line filter just outside of engine compartment under car next to frame that looked like it had never been changed - partially clogged - replaced it.Almost ran but would not keep running. I had rotor and cap pulled - found that the screw holding rotor in place was loose. The rotor edge next to plug wire leads was chopped up and the cap's plug wire leads were heavily oxidized. Replaced them and got it running but a little rough. Pulled the spark plugs and found gaps from 25 - 100 ---replaced the plugs with correct gapping and it ran really well.

Replaced bad fuel pump, installed new relay and fuel filter, engine turns over but is not firing on..... positive the fuel pump is pumping gas and checked to see if gas was going thru fuel filter. Tried...


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.

98 jimmy starts... but then dies and will not start back up untill later,changed fuel filter


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.

Vihicle died won't start


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
