My 86 SE is not starting, First we thought it wasn't getting gas, so I changed fuel filter while also changing the fuel lines a couple times (it kept leaking so fuel is at least going through the fuel pump), I've put a new distributor with a new cap and ignition coil, new ignition wires and spark plugs, it started once before and ran but when I put it into drive it just died out and haven't gotten it started since, that was after changing the distribution and all that but before changing the fuel filter, at this point I'm all out of ideas

Edit: it is the 2.8 v6, automatic, my bad for making y'all guess

Yes, when I changed the spark plugs, ignition wires and distributor, the only problem we was having was the timing, but I got that figured out and it started running, but that was when I put it in drive and it just died out

Air, Fuel and spark

Suggest getting a fuel pressure gauge and checking fuel pressure.
The fuel pump is located in the gas tank, there is a rubber compression connector between the fuel pump and the hard line. They age and can split. This causes low pressure and if it gets bad enough will cause the car not to run.

Bypass the fuel relay and turn on the fuel pump to test pressure
https://www.fiero.nl/forum/Forum2/HTML/144192.html

Check for codes
https://www.fiero.nl/cgi-bin/main.cgi?ECMCodes

Car could die when shifting into drive if the TCC solenoid is bad.
You can unplug the connector and try again but this alone wont stop the car from starting just when shifting into drive.

When you turn the ignition on (without starting), can you hear the fuel pump come on for 1-2 seconds?

When turning it on, the fuel pump does activate, but I've been slowly killing the battery and I don't have a charger at the moment, using it on a different car

So you had the ALDL jumper in place while you used a timing light?

We're supposed to guess.

I suspect it's the 2.8... but you never know!

No, but during that time, when we was putting the distributor in my grandpa was helping me with it and he rebuilt the engine beforehand, told me that as long as it was very close, it would start and run, run bad but it would run

Why not do it properly? All you need is a paper clip... and a timing light of course.

If you hear the fuel pump run for a few seconds when you first turn on the key, then we will assume the fuel system is working.
Do you have a timing light to verify the ignition system is working?

That's your problem.

The ECU is adjusting the timing, the ALDL must be jumpered to time the engine.

Good question Patrick.

After replacing the Distributer you have to get it close.
Find TDC and adjust the distributer so spark plug one is pointed to the number one plug on the distributer. That should get you close enough so the car will run then you can use the timing light to get it set correctly after its running with the jumper in place.
Finding TDC is the trick. You can pull the valve covers and watch the intake valve and verify the timing mark is correct. Pull the spark plug and use a soft rod and slowly rotate the crank until you know you are at TDC

Setting your initial timing will get you in the ball park until you can get it running and timed correctly.
Balancer marks can shift that is why its important to verify TDC and not just trust the mark on the balancer.

its a SBC but its the same process.
Good luck

That is incorrect... which is why it ticks me off when people state they have an SE and expect us to know what engine they have. It's not a GT. It's not a Formula.

The piston is also at TDC on the exhaust stroke...

I pull spark plug #1 and stick my finger in there as I manually turn engine with ratchet/socket.
When I feel the pressure building, I bring the timing mark up to 10* on the pointer. Reinstall plug.
(you could use a compression tester if you have one)

Then I remove distributor cap to make sure the rotor is pointing to #1 plug wire and they are in correct order 1-2-3-4-5-6

Always starts
(unless it's a fuel or ECM issue)

Just make sure it not like these. Results may vary.... Hint... plastic coated.
