    They said when they checked it there was no fuel pressure. We got it started and drove home last night about 25km. when we got home I shut it off then tried restarting it and it started. If it was the fuel pump would it start again? What about the trottle poisitioning sensor?

    The vehicle had a bad ignition switch so it was taken to a reputable technician shop. He charged nearly $350. to do the replacement and said he had to drill it out to replace the switch. Now the key has some play inside of the ignition and the battery drains within a day or two. I have taken it back twice and the problem has yet to be fixed. Any solutions?

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.

    The t.p.s is for idel control if thats bad it would stall, but start back up, The only thing i can tell you is it may be working now but what happens when it won't start the next time,or quits when your in the middle of a bussey road like a e- way Fuel pumps are a very common problem with all G.M. cars and trucks, on this site at least 5 out of 10 are fuel pump problems or fuel related. The best thing to do to guard aginst fuel pump problems is chg. fuel filter regularly and don't run around alot with less than 1 /4 tank of gas.

My 98;jimmy will not start engine turns but will not turn on

check for spark at the plugs then check for fuel. if one of these are missing the car won`t start. common problem on some of these was the ignition module in the distributor and sometimes the pickup coil wires would break. another thing to check is the distributor cap and rotor for damage like a cracked cap or burnt through rotor. fuel pump were also common.

1999 GMC Jimmy will not crank when moisture in the air or raining. Cranks after several days of dry air.

What brand of distributor cap did you use? When you say it won't crank, do you mean it won't even turn over? Or just turn over and not start up?

2001 GMC Jimmy with a 4.3L V6 auto trans. Will not turn over

The starter relay may have a bad connection, this is where your battery connects, and a power wire runs to the starter, also these have a ignition wire which is approx 14-16 gauge wire. The relay could be cracked or the contacts inside are going bad. But the other is the neutral safety switch that you mention. I would check these first.

Won't start

check the IAT(intake air temperature)sensor, if its bad may cause a no start situation and flooding,also check foe fuses to the ignition system and voltage to the coils

Spark after i changed distributor cap but wont start

sounds like you haven't indexed the rotor correctly or the cap isn't seated correctly.  Did you replace the plug wires correctly?  Dis you bump the position of the distributor?

Wont start in rain

Jimmy fx:

Since it is moisture related I would suspect the ignition system. My F150 pickup started running poorly and on a hunch I replace the plug wires, the distributor cap and plugs. It made all the difference in the world

Good luck Loringh
