I have a 2000 Grand Prix (3800 engine) the car will not start. It will kind of start if I give it a little throttle. What could be wrong?

I have change all plugs and wires. I checked all plugs for spark and all have. I pushed on the vlave on the fuel rail and has pressure and gas. I changed out the Crank sensor. Still will not start. The car was running fine, last week I drove it home from a hour away got home, stopped the car, went out 20 min. later and the car would not start.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Hi, the only thing common between the fuel pump circuit and the ignition circuit is the ECM itself. Recommend you check the ECM fuse. Not sure if it's in the car or the engine compartment fuse box. If this isn't the problem, you may have 2 separate problems. Your car doesn't have passlock anti-theft does it?

SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

My 1999 grand prix 3800 v-6 stalls when stopped and hesitates around 2000 rpm

tough one, has many things that could be wrong..to give you some idea...Air filter, a loose air hose, gas filter,oxygen sensors, sparkplugs wires or even crossed wires will all play a role in the hesitation that your car is producing, I have 2 grand prix and one of them is hesitating on me right now, I know its the oxygen sensor but I cant fix it now, dont have the money to. I know it wastes more gas but oh well for now! Try testing first.

Can I clean my Maf sensor and throttle body myself on a 2000 pontiac grand prix GTP? What are the steps? Is it necessary on 94,000 miles.

Yes it will help car run better. Take off any hose that goes to card so that you can see down throttle bore. Start car. Grab throttle linkage and figure out how to move it so that you can make the engine go faster. Begine to spray inside throttle body using little red hose that came with carb cleaner. While you are spraying the engine will try to cut out move the throttle linkage to speed up the engine so it won't cut out. Keep spraying all around inside and outside throttle bore.

04 grand prix shuts off

My 04 Grand Prix was doing the same thing. Not sure if what I found was the reason for it, but I removed the air filter portion of the intake, reached into the intake a little pulling the throttle plate down. It was caked in carbon build up. With a lint free rag and some throttle body cleaner, I scrubbed the plate and since have not had anymore issues with the car not starting. Hope this helps anyone.
