did you check the fuel pressur on the fuel rail with a gauge or did you just unplug the pressure reg..

also you should try replacing the fuel filter first... this is cheap 6-12 dollars autozone. just becuase the fuel pump is pumping doesnt mean it its enough. There mightbe a strainer on the fuel pump that might be plugged.

Could be fuel pump, is the pump running when you turn key on, you should be able to hear it. You are likely going to have to take it to someone with a pressure gauge to make sure it is getting proper fuel pressure. Fuel pumps commonly go on these vehicles

SOURCE: 95 gmc jimmy rough idle fuel in exhaust drives

Purchase new egr valve gasket with screen on it. The motor as it get older produces more carbon it then begins to break off and when the valve opens it get caught in there. i have cleaned mine several times and finally found the gasket at napa for around 22 bucks. All you need it 10mm wrech and 10mm socket with ext. takes around 10 min to do.

SOURCE: my 95 gmc will not atart i changed the fuel tank

If you do have fuel pressure, but there is no fuel getting into the cylinders to run the engine, then the engine does not have an injector signal or pulse to open the fuel injectors.

The ignition module and the pick-up coil/stator located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil. A faulty ignition module can cause any one of these systems to malfunction.

That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores. If the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show an open loop or an infinite reading between each wire and ground) and if the pick-up coil/stator is found to be faulty then replace the entire distributor, or the distributor will have to be dis-assembled to install a new pick-up coil/stator.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

My 1992 gmc has no spark and the fuel injectors dont work. why?


Check to see if when you removed the main plug and reinstalled it none of the metal fingers were bent in the computer. It has happened in the process also add some dielectric grease to keep them from grounding out.

95 gmc safari 4.3l just quit running, has compression, has spark, fuel psi is 10 when i turn it over


The fuel pressure should be alot higher im thinking around 60 psi but I dont remember exact. You most likely need a fuel pump. Its in the gas tank you have to drop the tank and change it out hopefully you dont have alot of fuel in it.

I have a 95 GMC suburban and my husband was on his way home and it died on him. it has gas in it and tries to turn over but wont start. what could it be?


What your going to have to do is have the fuel pressure checked.The pressure has to be 9-13 psi.If you have the 5.7 engine.If it is a 7.4 then it has to be 26-32 psi.If you don`t have a pressure tester then try tapping on the bottom of the fuel tank and if it starts then replace the fuel pump.If this is good then check for spark at the spark plugs.Let me know what you find.Good luck.

Is their a fuel pump in tank of E350 7.3 diesel 1988 ford ?


my guess is there is a fuel pump in tank as there are in 95% of diesel motor vehicles. you may have just sucked out the existing fuel from the lines. the fuel pump can withstand high amounts of amperage and voltage so by hooking up wires wrong i dont think you burned up the pump but you may have wired it up wrongly, or you have forgot to put the o rings back inthe housing properly. or drop on in tank. check the fel system setup. Orings in place, wiring connected properly. if all else fails give the pump a hit and see if it will start.

1997 gmc sierra p/u 5.0l 2wd needs fuel pump


NO dont drop tank, you will be sorry, take bed off, only like 6 or 8 bolts, and you will have more room to work, and its a pain in the *** to undo the lines and drop the tank, you cant get in there to do it, but just basic tools nothing special, be sure and try not to make any sparks while takein off that ring to get the pump out, and put an ac delco pump on there
