No spark to engine 1991 ford pickup


It can be faulty or dirty spark plug itselfd.Also for reference get the fuel level checked.Is the fuel tank is empty or near to empty.
Try cleaning the spark plugs and then see if that is helpin.On some cases the black carbon layer gets collected on the spark plugs and that causes the problem,so cleaning the plugs help.But if its not helping,then spark plug has to be replaced.Spark plugs get power from ignition coil to ignite sparks.If ignitioncoils are faulty then also there will no spark.--------------

I have a 350 chevy engine using a mallory unilite distributor what is the spark plug gap for champion platinum plugs number 3025 the engine is 1978


Without any more information than this I have to say it should be between 32 and 35 thousands. I don't have the info from the ignition system that your using, Have you checked the manufactures suggestions. Unless this is a super spark ignition then the gap I quoted should work.

1978 Chevy c10 pick up v8 350 my truck keep die even wen i chang gears i replace the fuel pump and check the spark pulges and check the vacuum it was good


Manual/automatic?? If automatic your torque convertor is probably going bad or your clutch packs in the tranny. If manual your clutch is gripping too much or not releasing properly

You either have a bad spark plug wire or coil pack. The light gray color on plug is normal.

64 chevy 250 ci firingorder


Haven't got a picture currently but firing order is 1,5,3,6,2,4.
cylinders are 1,2,3,4,5,6 from front to back. You should be able to use distributor & rotor position, at TDC to get where you want to be. Rotor turns clockwise. As long as you remember roughly where vacuum advance was pointing.

Chevy 350 engine


Was this engine apart?
If so, could be valve lash adjustment. too tight will cause predetonation, however a bad head gasket can be a culprit also. Do a compression check on both cylinders to determine. If your loosing coolant, good bet it's a head gasket. However, a cracked dizzy or carboned up cap can cause it also. I will tell you it's not a timing issue.
