Have1999 suburban k1500 5.7. have spark out of coil but no spark at plugs. have changed rotor and cap several times what else could it be.need wiring diagram to see where wire out of distributor goes...


If you can tell me what color the wire is I should be able to tell you where it goes.
But if you are getting spark from the coil tower the primary ignition system is working.
Have you checked the coil wire, and will it fire a plug ? The coil could be weak enough to fire a plug in open air but not in a cylinder under compression.
You do know for a fact the distributor rotor is turning, right ?

How do i find a large miss in my 1999 gmc suburban?


Check the firing order for starters as 2 crossed wires give a symptom similar to yours. Have the fault codes read first as that can save you real money in finding the fault. Have a compression check done to eliminate a blown gasket between cylinders.

You have likely crossed some of the ignition wires. Recheck your firing order and wire placement.

I have a 1999 chevy suburban 5.7 Vortech witch is starting to drive me nuts. The spark plug wires, and all around the ignition coil is arching. With this said the distributor, cap, rotor, plugs, wires, and...


Assuming none of the wires are crossed, AND you replaced the cap rotor wires with quality replacements (meaning AC Delco) then you may have a bad coil. Remove coil from dist cap if HEI and look for any signs of arcing such as blackened areas.

1999 chevy 350 runs rough at idle. #4cyl misfire. light gray build up on spark plug. compression good 180.


You either have a bad spark plug wire or coil pack. The light gray color on plug is normal.

Replacing spark plug wires


It's gotta be 5.7 V-8 . As u stand in front of the suburban facing the front bumper, there are 4 spark plugs on each side of the engine. The front (of the engine) plug on the drivers side, is plug #1, the front plug on the pass. side is #2, then back to driver side, next plug back is #3, back to Pass side, next plug is #4 etc. to #8. The distributor cap (spark plug wires go from dist. cap (9 wires on top) to each spark plug, Extra wire goes to coil, which sends spark to all wires). The wires fire in the following order: 1, 8, 4, 3, 6, 5. 7, 2. You will have to find where the #1 spark plug goes in the distributor cap, some (hopefully yours ) have a #1 on the top next too where the wire plugs in to the cap. If u find this u r good to go! Put #1 wire in, using a pushing/twisting motion, the wires go in in a clockwise order from #1 as u look down on the distributor. Wires to spark plugs go on w/ same push/twist. You should hear/feel a slight click or snap (not always though!) if inserted all the way. Let me know if this is enough info, if not I'll try to give u more. If u can't find where #1 goes on the dist. cap, stand on the driver side of engine, I believe #1 is at approx. 8 oclock position on the dist cap. Good luck!
