crank but won't start
I have 1997 chevy 5.7 it will crank all day long but
won't start there fuel in the line the fuel pump
comes on any ideas would be great
Fuel pump may be bad. Squirt some staring fluid or a little gas down the throttle body to see if it fires up. If so check the fuel pressure, it should be 56 to 63 lbs.
Check for spark if it won't run on the starting fluid. Get a screwdriver and remove one of the spark plug wires from one of the spark plugs. Insert the metal end of the screwdriver in the spark plug wire boot and hold the metal screwdriver close to something metal, that's not painted. Have a helper crank the engine. You should get a spark that you can see and hear. It should be a good strong spark that makes a SNAP-SNAP-SNAP type of sound. If you have that and it still won't run on the starting fluid, time to do a compression test. If all cylinders test low or zero it's jumped timing. HTH. -Jim
