No fuel, but cranks well!

Do you have a CEL?

What is the resistance of your Crank position sensor?

I do have a CEL, but it also may be from my purge valve not being connected...

So where are you venting the throttle body to? Do you have it sealed?

I have an end cap/vaccum cap on the end coming off the TB. PO had done the M50 swap previously and deleted it. Then now im doing s50.

Just checked resistance on my crank position sensor, reads .535K Ohms, or 535 ohms in other words. I believe this falls within tolerance if I have searched the other threads correctly...

did you remove the engines wiring harness at all? if so go back with the ETM and make sure you plugged all the sensors and accessory's into the right wires, some of them are very easy to get backwards, and depending on what they wont let the engine run. This was my reason for not getting spark or fuel when i first did my swap,but i cant remember now which 2 it was that i got backwards...

Have you checked the relays?

To answer your question, no I did not retain my harness. I got a new harness.

No I have not. I dont have any spare relays.

That wasn't what I meant by check the relays. Have you checked that the correct relay is within the correct plug? 5 prong relay to 5 prong plug, 4 prong to 4 prong.

The reason why I ask is because when I purchased a motor for one of my customers swap, they changed the relays around which caused the car to have the same symptoms. No spark, no fuel. Everything check out, and it was just mixed up relays on the wrong plugs.

Oh, sorry, yes. I checked and the 5 prong relay is in the 5 prong slot, and the 2 4's are in their respective slots. Now Im wondering if these 2 relays that have 4 prongs are the same or not, or if i can switch them around to test...

Relay testing.

For the picture.

Apply +12V on pin 86
Ground to 85
Read for voltage (+12V) on 87
And use -12V on your ground on the meter.

You can check the 4 pin relays that way.

The 5 pin relays if I remember correctly will have a 87 and an 87a.

With power you should have 12V on one of them
With no power you should get power through the other.

Put a jumper in between 86 and 87 to bypass the fuel pump relay for now. For testing.

555 is fine for the CPS.

Did you meter that @ the ECU connection ? (x6000)

I metered it by unplugging the CPS from the harness, and puting the two test leads on the volt meter on 2 separate prongs.

go back and make sure you plugged everything in correctly, Use the ETM and go by wire color, its VERY EASY to plug something in wrong, and 1 thing wrong could cause all the symptoms you have.

Check ground at the DME.

[jahnaboi]

You guys do know that the ECU has an internal ground right?
