Hi there I will do all I can to help. Do you have access to a scanner? What you need to do is check for spark and for fuel, because you said that you installed a fuel pump, then we could assumne that the fuel is getting there, check if you hear the fuel pump running when you turn the key to the on position. TO check for spark remove one of the sparkplug wires and connect a sprakplug to it and ground the sprakplug, next have someone turn over the vehicle, you should see the sparkplug sparking.

I have a scanner and it said cylinder 5 misfire and evap system leak (small leak)I did check for spark and it was goodFuel pump turns on cause I hear it
Automotive Expert
ok is your scanner capable of reading live data? check if you are getting an RPM signal when cranking.

I ll contact again tomorrow in morning.When iam working on the truck

Automotive Expert
Hi there

Ok so I check and I am getting reminded when crankingRpm
Automotive Expert
Ok next thing I would check would be for compression start with cylinder 5

I did try starting fluid as well still wouldn't
Automotive Expert
I dont think the starting fluid will make it work, if the fuel pump is working and there is spark it should at least attempt to fire. can your scanner read live data?

I did research and on my make and model truck has a spider distributor cap and when it goes bad I can get misfire fire and it not even startIts Christmas now so I can t get the part but I will tomorrow
