check to see if you have your plug wires at the right location on distributor cap. If you don't have a digram they are as follows- right side 1, 3, 5 front to rear. Left side is 2,4,6 front to rear. #1 should be on the location at front of cap closest to intake manifold. firing order is 1,2,3,4,5,6. Hope this helps. KS

on that engine the crankshaft sensor sends a signal to the pcm to fire the coil the pcm then sends a ground pulse signal to the coil to fire if you check for 12 volts at the coil and it is there with the key turned to run. then use a 12 volt test light hooked up the alagator clip on the positive battery post and touch the probe end of the test light to the pulsing wire at the coil electrical connector white and black wire during cranking the test light should flash.also test pink wire at coil connector for 12 volt with dvom for power.if no 12 volt check fuses with the test light to ground on injector 1 fuse. also ohms test the coil wire no more than 1000 ohms per inch . also check ground at ign module with the test light .Hope this helps thunder boltz please post rating

Did you replace the sending unit on the drivers side head between the number 1 and 3 spark plugs? That is the one for the gauge

Check to see if you have compression on all cylinders. If you don't, replace the timing chain/belt. If you do check the ignition relay and fuse panel for blown fuses.
