I just picked up an 86 with the 2.8 and manual trans. I need some help getting this thing running... The car turns over but will not run... Here is what I have done or checked...
1. Spark to the plugs (really just checked one of them) 2. There was zero fuel pressure at the valve so I changed out the fuel pump and sending unit. 3. the ECM, Distributor Cap and Rotor were changed by the previous owner just before I got it and I had the ECM tested it was fine on 3 tests... 4. Fuel Filter changed. 5. Coil tested with volt meter
It will turn over but will not run. When I pump the gas it makes a "popping" sounds.
I really need some help... What am I missing? What could it be?
Do you know the history of the car? The popping sounds suggest that it is getting both fuel and spark, but not when it does any good. There could be a timing issue as well as a few other problems...the first thing to check is if the spark plug wires are in the right place. Has it run since the parts were replaced?
The wires are in the right place on the Dist cap 1-6 according to the diagram I found on line. Is there an easy way to check the timing? I am not sure when the car stopped running but I believe it was after the cap/rotor were replaced. - but i am not sure...
Thanks, Rob

Sounds like the timing was messed up during the "tuneup".
You have to get cylinder #1 to TDC and see if timing mark lines up. Then check that rotor is pointing to correct cylinder #1 spark plug wire.
Also, fuel pressure should be 42 psi at "Key On"...
Check the fuel pump relay. A quick check is to switch out the connector with the one next to it. Make sure you put a piece of tape or mark the connector so you don't forget which is which.
Check this site. https://www.wc-autoparts.co...-6-cylinder-engines/ It has the firing order and the spark plug location as well as where the number 1 plug lead is located on the distributor when the timing is set correctly. Cylinders 1, 3, & 5 are located closest to the trunk compartment. The transmission will be on your left.
Sorry for the newbie question... but... The spark plug wires are in the right places. When I tried to start it using starter fluid squirted into the intake it backfired and lit the fluid on fire! That was fun!
Can I check the timing without having to remove the timing chain cover etc... any help would be appreciated!

Checking/changing the ignition timing has nothing to do with the timing chain. It has to do with rotation of the distributor body in relation to the rotor.
You also need to buy or borrow a timing light.

That tells you that the spark happened before the intake valve closed....way too soon to be useful. It's possible that the rotor is not on the shaft right.....pointing backwards.

After looking all over the internet I found one guy who suggested switching the wires on the Distributor cap http://www.gafiero.org/bbs/index.php?topic=1415.0 1 to 4 2 to 5 3 to 6... it started right up!! Sounds good! Thank your everyone!
