Check the fuel pressure. It has to have 60 psi or it won't start. These are common for having weak fuel pumps causing this problem.

I have a 1999 GMC jimmy 4 door 4x4 v6 4.3 ltr automatic with a starting problem, it starts with starting fluid and runs great afterwards can drive all over God's creation afterwards, but day a


Sounds like you are loosing fuel pressure overnight. Since it takes 70+ psi to start and run, if you have zero pressure in the morning, it would take a long time of cranking to get the pressure back up.
If it is low or no pressure, the problem could be a faulty check valve in the fuel pump.

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?

Can you jumper the fuel pump and make it start and continue to run ?
Have you checked to see if you are getting spark when it won't start ?
Could be a relay or coil, ignition module, or other component.

1999 gmc 4.3 jimmy 4 weel drive, service engine light on, will not start


The first thing i would do is have the computer scanned for codes and see what codes are stored, you may have a bad fuelpump or a control module problem, check for fuel and spark, spray starting fluid into throtle and see if it starts if it does then you know its a fuel problem.
