Alright guys, I've got a head scratcher...

96 5S Auto Vert.

Cranks, but won't start.

FUEL: CONFIRMED
SPARK: NONE
UPGRADED GROUNDS: COMPLETE
IGNITER: REPLACED
COIL: REPLACED
CRANK POSITION SENSOR: REPLACED
ECU: CHECKS OUT OK

The car was running fine with the occasional P1300 code on the first cold start of the day. Didn't affect drivability. We got some serious rain here this week, now the car will not run.

I've gone over this car top to bottom and cannot figure out why it won't start.

Now, if the car is cranked over, and the coil wire is pulled to check against ground, there is no spark. (I did the test all the way up to the coil itself to rule out wires)

YOUR CLUE:

With the key on, and all connectors plugged in, if the igniter is removed from it's bracket, it will arc like when the positive battery terminal is first connected.

If the coil connector is removed from the coil, the arcing will stop.

Last night, I got the car to run for about 15 seconds, as I was holding the igniter to one of the strut bolts to ground out the housing. After that, the igniter housing didnít/wouldnít arc anymore, nor could I get the car to run again.

Iím lost now. Help?

Does it work if you hold the igniter to ground and hold the coil wire in your hand while stac is cranking? laugh.gif


Over at Toyotanation there's a glut of problems with aftermarket igniters, pickup coils, and ignition coils. Do you have a running 5S to swap parts from to test with? Like literally 95% of the problems are bad aftermarket parts. http://troubleshootmyvehicle.com/toyota/2....l-module-test-1 for a camry but looks like a pretty solid set of tests. It sort of sounds like the bracket it's mounted to isn't grounded anymore or it's case bottom isn't grounding to the bracket, can you run a jumper cable from one of the mounting screws to a good engine ground or to the battery negative post? If you put a noid light on the ignition coil it should flash like a fuel injector if it's all working correctly. To make things easier on everything pull the plugs and disable the fuel pump while testing so you don't flood the engine and run the battery down fighting compression.
