my 5th gen max

I recently bought an engine from a junk yard with a 90 day warranty. Prior to intstalling I had to take off the flywheel because it was a screw behind it loose.I put it in and the car won't start unless I put some gas or starting fluid in the intake, but it cuts right back off. I changed the fuel pump, fuel filter and fuel pump relay. Still only starts with the fluid or gas. So I bought a used fuel pressure regulator and it sounds like it wants to start more, but still won't start without starting fluid. I didn't change the sending unit that the pump goes in because I think it's good because when I turn the key I hear it prime. So I disconnected one of the fuel lines at the engine(not the fuel pressure regulator) to see if it was getting gas. When I turn the key gas comes out for about three seconds, but when I try to start the fuel stops coming out. What could be the problem? Any suggestions or solutions please? Thanks in advance

P.S the engine was probably sitting for a long time because i had to clean the spark plug wells. It was oil caked up, but I wasn't able to clean them out completely, jus enough to see some of the metal so hopefully spark would catch. I changed the ecu, iacv, 6 coils(advanced auto parts), Maf sensor, cam sensor, harmonic balancer, water pump, all belts, fuel pump, pressure regulator, fuel filter.

Could it be a timing issue? How do I check that if the car won't start?
Ecu issue?
Crank sensor?
Knock sensor?
Could my injectors be clogged or no good?

are there any dtc's/check enegine codes?

Yea p1320 distributor signal interrupt. Ignition signal

I'm thinking I should reprogram my key of the Ecu

??? if ur using the same ECU u shouldnt have to...

In the OP post he says he had changed the ECU so that could very well be one of the issues with the fuel lines being shut down upon start up

I changed the ecu and had it programmed to the old engine which is a 2000 engine that has a choke. Then I swapped the engine with a 2001 engine that is the same but doesn't have the choke

um just curious, whats a " choke " ?


were you able to turn it over by hand with a wrench?


Do you have fuel coming out of the rail?


Do you have spark coming out of the coil packs?


have you done a compression check?


Is the flex plate installed correctly ? ( iirc they are keyed and only go on one way )

I am going to assume the engine was ok at the time of install and the sensors were plugged in , in the correct connector?

Its kinda hard to explain what the choke is, but it's something by the the upper intake plenum that has a lid that I believe is opened up when needed.

Yes i get fuel at the rail when I turn the key but when I try to start the fuel stops.

I know it's getting spark Cuz it starts when I put starting fluid in the intake

Every connector is hooked up right

No compression check done yet tho

What is a flex plate??
