Would you think that weak sparks on all plugs would be bad coil packs, wires, or grounding?
Why would the Foxwell turn on the fuel pump, but not your ignition key?

 

No, I've never dared use it on a gas engine, due to all the horror stories I heard growing up near the Canadian border. I'm sure it is safe if used properly, and I'm not arguing that it is not.....but old habits die hard.

 

 

You don’t have to “spray” anything. Remove PCV vent line from intake, dump a little fuel directly into the intake, re-attach PCV/breather line & try to start it. “If” it sputters or coughs = you have a fuel issue. If you get nada zip nothing you have a spark or CPS issue.

 

 

What error codes are you seeing via the Foxwell?

 

There was a voltage supply code in the ECU which I thought was from the battery being run down. I didn't find any codes in the bcu. I went through the other systems, only thing weird is it can't communicate with the cruise control.

 

I've heard of people getting no error code when they have a bad Crank Position Sensor (CPS). Cheap to replace.

A failed CPS would cause a no spark situation.

Maybe clear the codes, replace the CPS, and retry?

 

Well I can certainly try put the original one back in. I did replace it with a non bosch one from oreilley. According to the foxwell, it is showing cranking rpm, but maybe a bad/false signal???? My other thought was a bad coil(or two) and the used ones also bad, or wires are bad. The pug wires look to be recently replaced, but who knows.

PS, you mentioned getting the BCU/ECU synched(married) with the foxwell. The ECU date of manufacture and the vin number match the vehicle. How do you pair them to eliminate the flashing odometer?

 

Odometer will flash if the dash is not original (VIN doesn't match ECU+BCU). Maybe the Foxwell can put your VIN into the dash?
