Hi: Have owned 9 Blazers and Jimmy's. have never heard of a cold start switch on a Jimmy. If the engine is fireing I would rule out the coil for now. What you are describing sounds to me like low fuel pressure, if the pressure is not around 60 PSI then the injectors will not function correctly. If you have ever driven the vehicle for a while, stopped somewhere and it wouldn't start unril it has sat for a while then chances are the problem is the fuel pump located in the fuel tank.

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.

My 97 jimmy has no power to fuses at block to 4/5/10/16/20/ and no fire at plugs. is this an ignition switch problem or ECM ?


Those fuses are supplied by the ignition switch in the "start" position.
Either the switch is bad or the fusable link "B" in the underhood fuse/relay center is blown.

I have a 1997 gmc jimmy and it is hard to start when it is cold i think its a choke problem.


Hello,
The choke on your vehicle is a computer controled fuel system. It is usually a fuel pump but sometimes a Distributor cap and rotor problem. I would first check the distributor cap and rotor. Look for white corrosion in the cap and in the bottom of the distributor. If you see the corrosion in the bottom of the distributor clean it out with brake cleaner.The Coil wire some times fails causing a hard start situation. I suggest checking these things before doing any thing with the fuel pump. I would also replace the fuel filter and spark plugs if you do end up replacing the cap and rotor.

I hope this helps.

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.
