1G Wont turn over.. Help!

[tmota503]

Hey wats up forum, so im still in my swap to 4g63 n/a to 4g63t .

I got it to crank but it wont turn over, I installed a walbro 255.
Do I have to rewire it in order to work properly? Its getting fuel though.

currently im using the old spark plug wires. They have some carbon build up but worked fine in previous car. Would this cause it not to crank?

Alternator worked fine as well.

Other things I should check?

Ok, first off. Cranking is when you turn the engine over with the starter . Turning over is when you do it with a wrench or something. You mean you can't get it to start?
What did you do with the ECU?

 

[tmota503]

Im using the ecu out of the donor car. My bad. Yes I meant it wont start. I can get a mechanic to come and have it runnin for 100, but then again what if its something simple then I can just save money and upgrade turbo or whatever.

I'm using the donor cars motor, transmission, harness and ecu.

Cranking, turning over = engine spinning.
Firing or starting = engine actually runs to some degree.

Other than that Im completely unfamiliar with the swap your doing. Did the donor car run? Did you check the ECU for condition?

 

[phantom_19]

If it smells like fuel when cranking,the fuel pump isn't faulty. You might want to check the coils if they are still good. Not that all 4 injectors could be clogged, but did you check this as well?

 

[tmota503]

Om sorry again for the wrong words used

Gonna check my coils tomorrow.. Or later. Im off at 4am

damn I sold my old wire harness to clip off a injector plug in to test them..

So checked it today, and the coil pack is good, as well as the fuel pump.

how would I go checking the injectors?

I checked everything possible... And nothin..

Did you check compression?

 

[steve]

Does the check engine light turn on for 5 seconds when you turn the ignition on?
If it doesn't then it's very possible that the ECU isn't working.

 

[tmota503]

I havent looked into the ecu, I was hoping to do a compresion test just dont know how.

Would a ecu just go out like nothing?

They can and do, which is why I asked does the CEL turn on for five seconds when you first turn on the ignition?

There is a lot involved in the swap, including adding the wiring for the turbo engine injector resistor pack. Have you done that?

A compression test is simple, remove all the spark plugs, remove the MPI fuse, install the compression tester in a cylinder, open the throttle and crank the engine for a second or two and write down the values. Repeat for all the rest of the cylinders.

 

[tmota503]

Oh I see, ill check tommorow. I have the car at my cousins. Live in a town house that doesnt allow even a oil change. :/
I used the turbos engine harness too. Do I still need the extra wire?

What tool is that you use for the compresion?

Also I went from 7 bolt to 6 bolt. does cam angle sensor have to do anything?

The turbo wiring harness should have included the silver injector resistor box that bolts to the firewall. If you don't have it your injectors won't work.

Typical compression tester. New they can be found for about $30-$40

There is no major difference in the CAS between 1G 6 bolt and 7 bolt engines.

Yeah I have the injector pack connected and screwed on to the firewall.


Alright ill go check it out at a store tommorrow. Maybe buy some spark plug wires while im at it.

Anything else I should check?

Before you go spend any money, turn the ignition on and verify that the CEL turns on for about five seconds and then turns off. That's the first step. If the ECU isn't running then nothing else interesting is going to happen.

 

[tmota503]

I get you. But been wanting to buy some since idk when was the last time they were changed

Alright so I checked it out today and the cel light doesnt appear on the cluster.
Guessing bad ecu?

Next check is the MPI fuse on the battery to make sure it's not blown. Visual checks don't count. Pull it and verify there is continuity across it with a multimeter. Keep the multimeter handy you'll need it for the rest of the diagnosis.

 

[tmota503]

Alright gonna try and tow it home since all the big swap is finished
Other symptoms it has the windows don't roll down. Checked fuses and all good?

 

[steve]

Assuming you don't have a dead battery, the power windows need the alternator fuse (80A), fusible link 5 (30A), Ignition fuse (30A) and Multipurpose fuse 3 (10A) to work.

The ECU needs the MPI fuse (20A) and Ignition fuse (30A) to work.

Do your automatic seat belts work?
Does the dome lights work?
Does windshield wipers work?
Does the blower motor work?
Does the starter crank?

Each of these checks out parts of the various circuits and fuses.

Ahh I see, seat belts work, wipers work and blower motor works. It cranks yoo. I have a new napa battery.
Did take off the black tube box under the battery tray. Fuel somethin I forgot.

So timing was off. We checked evet fuse twice. But timing was bad. Gonna start a new thread for why the cam moves losely.

I've read alot about bad CAS causing alot of no start problems but it seems swaping into a NT car is a pain in the ass so it could be anything, I would do everything steve says because he seems to know whats up.
