Follow one of the spark plug wire to where they all are. if no cap found but ignition coils, your model doesn't have any

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?

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.

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?

Set timing 1997 jimmy


Ok that's pretty simple Put cylinder # 1 on TDC= top dead center on the (compressionstroke piston all the way up). Mark on metal part of distributor (with marker) where the number one is on the cap( that's where the number 1 wire plugs in) Then in-plant distributor make sure that rotor point is pointed to #1 on the cap, turn distributor shaft until this is achieved or as close as possible try to center shaft so you can adjust... ****** or advance to fine tune after you in-plant distributor if needed. Contact if you need more help . Good Luck
