How to start my engine after engine swap
10

Asked by Steven Jan 11, 2020 at 10:46 PM about the 2003 Chevrolet Suburban 1500 RWD

Question type: Maintenance & Repair

I have tried everything to get my 5.3 liter engine
running. I hooked the computer up to it and it gave
me a code PO335 that was the crank shaft sensor
but I bought a new  one but it still would not get
any fire and the injectors won't spray. And I have
checked all the wires and everything is good. What
should I do please help.

Did you install the wrong version of the 5.3? If the reluctor wheel is different it will never run without the correct ECU.
