I own a 1990 Chevy Suburban (350, 5.7L V8) (not rellay a Hot Rod, but I have always had a thing for the tank)

anyway, the truck has stated to backfire. It "was" doing it just after startup and continues unitl it is put into grear. After about a mile down the road, it backfres off and on ( no pattern) The backfires sound like they are comming out of the exhaust.

I spoke to a loacl mechinic and he sugested a change of the plugs, wires, and cap and rotor. I just now finshed the sugested "repairs" and as i was replacing the plugs noticed the the plug in cly #8 was loose and had oil on the nut.

after replacing the cap and rotor, i atempted to start the truck. No go.

I am prety sure that i put the wires back in the correct positions. so I am stuck not knowing whats wrong.

The engine wont even spin now, and i know the battery is good

All I hear when i try to start it is a fast ticking that sounds like the starter is not getting enough juice. the battery conections are tight.

could it be compresion related? IE: too much

If I have messed up the wires, how can i get them back in the right positions?

And why would a missplaced wire casue the the engine not to start?



This is a "daily driver" and i need to get it back on the road asap.

Any ideas or sugestions would be greatly appretiated

thanks

Charles
