The ECU doesn't turn the pump on at cranking speeds. That's why the Circuit Opening Relay has a starting coil. And the engine wouldn't run at all if the CPS was faulty. It wouldn't run and then die....it wouldn't run period because no NE and G signal equals no spark. Not mention he'd have at...

There aren't any hoses under the intake? Sure about that?

^ My thoughts too. Also I believe in the original thread I suggested the OP pressure test *before* putting the dash back in. And considering the amount of work involved I would've replaced the core with new...

^ Well, you need to define cranking. The CPS isn't involved with the starter turning the engine over. OP: On a GTE the fuel pump runs when the key is held to start. That function is completely independent of the CPS. However for the pump to continue operating after engine start/key release...

Lmao. Tough crowd ;) Not helping your case any....

It's spelled "dual"...

Photo in post 4 and text in post 8 imply one guy is talking CPS while the other is talking TPS. The confusion could've been avoided if both had paid attention. That and the OP's posts aren't exactly coherent...

California has three smog check programs: Enhanced, Basic, and Change of Ownership. Enhanced means the vehicle gets put on the dyno and tested for NOx. Basic means the old two speed idle test. Change of Ownership means the vehicle is tested once when ownership changes or when initially...

Fwiw there are lots of online places to get one for half the price Napa charges. Or you could go to the nearest pet store and buy a $5 aquarium test kit. Same chemical indicator (dibromothymolsulfonephthalein), same results...

^ Needed for serious work but in this case a meter will work fine. OP: Fwiw backfire is an induction system event. I assume you're talking about after-fire, aka muffler explosion...

For once the monkeys at The Shack are correct. I see no reason this needs to exactly equal 2.5K either. Try a 2.2K ohm 1/4 or 1/2 watt. Common as dirt....

You were a victim of questionable cause logical fallacy. As previously stated it's not possible for bad CPS wiring (or a bad CPS for that matter) to prevent cranking...

Let us know how the new relay works out. I hope it wasn't expensive...

He didn't say what rpm it cuts out at but it could be the IDL contact isn't opening or is intermittently shorting. That results in rpm cut, something that sounds similar to his symptom. He should: 1) Jumper T and E1. 2) Key on, engine off. 3) Slowly press gas pedal to the floor. 4)...

Actually it's what codes he doesn't have that could point to the problem...

Sounds like it's open but if not be sure you don't energize it too long. The speed sensor is integral to the speedometer. It can often be fixed with a little care. A quick way of checking it is to use the cruise control diagnostics...

Gee, I dunno. Maybe page BE-84?

None of the ABS sensors are involved with operating the PPS. And whether you can live without ABS has yet to be determined...

Maybe so but some use steppers for better control.
