SOURCE: 2000 GMC Jimmy will not start

The oil presure switch does have some bearing on the problem but my suggestion is to change the coil. I had a the same problem with an astro van. I changed everything that you have described and it fixed the problem just for a little while and then all of a sudden did it again. I changed the coild and the cold start swithch and never had the problem again.

I also had this problem with mine. There's a main power cable that runs to the battery. The bolt was completely corroded, so there was no connection = no power to start the truck. Check that, it'll cost ya less than 5 bucks to fix.

When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

My 2000 jimmy takes about 10 to 20 engine cranks in the morning when its cold out.when it starts its good the rest of the day. but its getting worse the amount of cranking the engine over in the morn


I'd use a fuel pressure gage, check fuel pressure, key on, engine off, first thing in the morning, 60--66 psi, spider fuel system. If you have the spider fuel stem, that system is noted for problems.
There is a service bulletin for cold start-up problems, caused by fuel poppet valves sticking. Once you get it started, it runs fine the rest of the day. The poppet cleaning procedure shows to be a shop procedure.

I have replaced countless distributprs for this issue. also fuel pressure has to be abovr 50 psi or will not start needs 50 pdi to open poppit valves on injectors. also if the spiders ruptured will be to much fuel and won't start hook up fuel gauge turn key on till reaches max psi turn the key off shouldn't loose more tham 15-20 psi if it does suspect spiders leaking.

A 1998 gmc Sierra driving down road at 60 and it just died replaced ignition module and in line fuel filter and now It won't even try's to start


Have you checked the fuel pressure? I think that the fuel pressure is between 55 or 60 pounds. They won't run under 52 pounds.

It can take 70psi to start a vortec engine cold. It should start on starting fluid tho.
You might want to look at a couple of spark plugs to see if they are in good enough condition to run. The spark could be weak under compression if the plugs are worn.

Could possibly be the anti theft system. Check out this link. When the SECURITY fails, you should see a light on the dash that says security. A symptom of a failed anti theft is starting for 1-5 seconds and then stalling repeatedly. http://vatspasslockpasskeysecurityhelp.yolasite.com/

2001 gmc jimmy not starting


Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

2000 gmc jimmy won't start


Could be your fuel pump. These vehicles are known for fuel pumps couing out. Sometimes you can hit the bottom of the fuel tank and get the pump to work for a limited time. Check the fuel pressure at the fuel rail to see if your pump is working. If no pressure at the fuel rail then you will probably be looking at a new fuel pump. If you have pressure and the pump is working then it could be a list of other things. Try also listening for the sound of the pump priming when you first turn the key on. Should be able to hear it for the first few seconds. Hope this helps. Good luck and let me know.
