No Spark!!
« on: August 26 2015, 03:19:25 PM »
Took the car for a spin last night and it died on me.  The car has made a popping sound on me a few times out of the blue.  Last night it made a popping sound again, drove for 2 blocks then it suddenly died.  I put a brand new ECM in it to try and I put the ignition module and coil from my other car as well as checked all fuses.

What do you guys think?  Crank sensor?

Fuel pump may have taken a dump, fuel filter clogged.  Running lean causes bad stuff to happen

Nice to see I am not alone.  So when you crank it there is no spark jumping to the head/header off an exposed spark plug/screw driver?

I should've asked that first.  I've seen guys run a car without the actuator line hooked up and wonder why it was popping,  Also seen a weak fuel pump be the cause of the popping

Fuel pump is brand new and I have lots of fuel pressure and oil pressure when I crank over the car.

Blown fuse, corroded (dead) orange ECM wire, stripped timing set, bad cam sensor cap, crank sensor, overtightened module plug........

Like I already said, the fuses are all good.  But I have a double roller timing chain without the tensioner, I'm thinking it could be way to sloppy.

I went to Steves site...and if you have no spark or injector pulse...have a peek at the crank sensor. Steve has an entire no start tree...which has pulled my ass out of the fire on more than one occasion. :)

Unlikely.  I only say this because have had a double roller w/o a tensioner in my car since the day it hit the road back in 2002.  It is more likely tied to something else.  Plus, I don't want to see you do all that work. LOL!

How bout injector pulse?

Is the compression normal?

A lot of broken parts does not make you a racer; it makes you a slow learner.

So, you have a gauge on it and can see pressure/hear the pump?
Is the cam sensor spinning with the cap off?
Coil pack has correct ohms across each coil?
No spark at the spark plug?

I have 45psi on the rail, did not check the cam sensor, I have the module and coil from my 14k car on it, and yes no spark at the spark plug.  Couldn't find my noid light but the laptop show 10 to 12ms when spinning the car over.
