2001 isuzu rodeo will not start after fuel pump replacement

Mechanic's Assistant: Have you ever replaced the fuel pump, or is this the original?

Replaced

Mechanic's Assistant: Are you fixing your Rodeo yourself? What have you tried so far?

Replaced fuel pump and fuel pump relay. After checking the ECM isn't sending power to the relay to prime the fuel pump during start up. Engine cranks but doesn't start. Also during cranking the security light flashes slow

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I have already replaced the ecm

Was the engine running before fuel pump replacement?

Customer reply replied 4 months ago
No. When i tryed to start it I noticed the fuel pump wasn't priming. After testing the relay ( it was good) I replaced the fuel pump.

Auto Mechanic: Dan, ASE Master Technician replied 4 months ago

Have you checked the fuel pump fuse? Try spraying starting fluid in the throttle body and see if the engine will run.

Customer reply replied 4 months ago
Fuel pump fuse is good.
I have no pressure in the fuel rail due to the fuel pump not priming druing start up. How would starting the car with Either help? Asking because I don't have any and will need to go to town.)
Auto Mechanic: Dan, ASE Master Technician replied 4 months ago

I just want to confirm that this is a fuel issue. Sounds like you know for sure that the fuel pump is not getting voltage. Do you have power at the relay with the relay removed?

Customer reply replied 4 months ago
12 v at the relay (87 to 30). But during startup NO power at the relay on poles that engage the switch (85 to 86.
Customer reply replied 4 months ago
when i jump 87 to 30 ( this bypasses the relay switch) it engages the fuel pump (priming) so I know it works.
Auto Mechanic: Dan, ASE Master Technician replied 4 months ago

Will the pump run if you use a jumper wire at the switch of the relay? This will verify the wiring to the pump is ok.

Ohm the wiring harness between the ecm and the switching side of the relay to verify the harness is ok

already did.From the relay: the ground is good. the wire from relay to ecm postion 42 is good. no breaks
I have also relayed the ecm
Auto Mechanic: Dan, ASE Master Technician replied 4 months ago

Have you scanned ecm for codes?

no, I can't move the car. Working on it in the drive way.
Auto Mechanic: Dan, ASE Master Technician replied 4 months ago

You said you replaced the ECM. Was the ecm programmed to the vehicle? the vehicle has an immobilizer.

Ask Your Own Car Question
Customer reply replied 4 months ago
When i sent a request to a shop they told me it was plug in play with no reprogramming required
Auto Mechanic: Dan, ASE Master Technician replied 4 months ago

It depends if your vehicle has immobilizer or not, and right around 2001 is when the Rodeo had the immobilizer.

The immobilzer will cut off fuel. The new ecm may not be recognizing the key.

Customer reply replied 4 months ago
I thought that too. So after I troubleshot the electrical, I ordered a used ECM. When i arrived as went to send it for reprogramming and was told it didn't need it. How can i be sure?
Customer reply replied 4 months ago
when it arrived I went*
Auto Mechanic: Dan, ASE Master Technician replied 4 months ago

You would need a scan tool to verify. Best would be to have the Tech2 scan tool.

A possible solution would be to have a mobile locksmith come out and program the key.

Dan, I tryed both of your suggestions. There are no codes and the locksmith came out and said the car did not need the key programed. Any other ideas?
