I am at wits end. No Spark at plugs. Diagnostic machine said Computer bad, replaced that, still no spark. Someone on this forum suggested the Crank Position sensor, I replaced that, same result.
I tested Voltage going into coils and Battery Voltage is present, Still no spark at any of the 4 plugs.
Can Not use code checking machine again because NEW computer. My next guess would be the coils themselves, since there is 12 Volts going in and Nothing coming out. Would it be uncommon for BOTH coils to go out at once?
Thank You and Blessings
Make sure the new crank sensor you installed is fully inside the block Make sure the old rubber o ring didnt come of of the old sensor and stay inside the block whie installing new sensor, I have seen this happen B4 and the crank sensor will not read the tone wheel on the crankshaft do to excessive clearence I really dont think its the coils, They are not firing because the computer is not grounding them for some reason wich could be a broken ground signal wire from computer or the crank sensor Also check all your fuses and relays

I plan to open the wire harness to check for broken or burned ground wire, or could I just probe pin 10 on the computer to see if there is continuity between it and GROUND
GOD Bless the people Whom share their knowledge!
