This A 1999 Chevy S10 Xtreme 4.3 the problem is it will crank over but will not start. We changed the rotor and cap. Check fuel presure and it was 60psi. After we changed the rotor and cap it cranks like I said but will kind of back fire. We had checked for spark and it has spark BUT looks kind of weak. This truck was running fine and one morning I went out and thats all she would do is just crank and not start please help thanks JEFF

Cranks but no start condition:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
