im in need of help. i have a 04 5.3, in a 88 cutlass. the car ran great for about two months, then one day it just shut off,, after checking the system[wire harness] i found that the two power wires that hooks to the starter and the crankshaft sensor wire had burnt into the header, so i bought a new stand alone wiring harness, once i finish installing the harness, the car started up but it had a really bad vibration so i shut the car off and rechecked behind myself to make sure everything was in its place as it should be, which it was so i restarted the car [still had a bad vibration] but it ran for 3 mins then shut off, in would not start again. so i went to checking the possiblities , i check fuel in which its getting 59 psi of fuel. i check all my grounds , they all had good connection, i check to see if the ignition was getting 12v and constant 12v which it was, i check to see was the the coils getting ground and 12v which they both was but i wasnt getting any sparks, so i check the crank and cam sensor with they was both getting power so i replace them just in case and still no sparks.. can anyone please point me in the right direction. on how to fix this..
