hi, I took the head apart to change the valve seals but finally I didn't do it. i put it all back to the right place and now it wont start any more. I put in new headers and throttle body at the same time. now the spark plugs ''on all four'' wont spark. I checked the wiring there's power but the coils don't give any to the spark plugs but it started before I took it a part... help?

Did u forget the ground wire tat was on the head against the firewall in the tight spot?

everything that i unpluged i re-pluged... i have pover in the wirer i check it with a tool for checking wires im thinking that all 4 coils went bad all at once??

franky

Its actually a wire tat is bolted onto the head. If u have a scanner handly, u can plug it into the obd 2 connector. If the car starts, then u have a ground problem n maybe u forgot tat wire. If the car doesn't start, then the problem is elsewhere.

Or u can just try to squeeze n look at tat wire. Its a pretty tight spot.

anything eles that could cause my coils from giving prower to the spark plugs?

franky

U can test them for continity or beeping sound with a multimeter or borrow the coils from another s owner.

Franky is referencing the ground reference in this location. Make sure it's there. Did you doublecheck your timing?

if the timing isnt right by like nothing the car wont start?? and all i did is take the valve cover of and the cams so i didnt touch that ground wire your showing me... its really the coils that arent giving power to the spark plugs

The coils are powered thru the PGMFI main relay and underhood fuse #46 (15A). If the pump is priming, your relay is fine.

Start with the basics and check your two TDC/cam sensors on the valve cover. Make sure they're mated properly.

Note: the coils are negative triggered by the ECU.

if my cams are not alined properly the car wont start ??
