Fule Pump or Fuel Regulator? Options

[chrispovoas]

Hi guys, so on my journey to get the engine running an pulling correctly I have done the following;

1) Tracked down all of the air leaks so that the engne stalls if i cover up the main air intake on the air box

2) Refurbed all 4 injectors

3) Replaced the ignition leads, Rotor and distributor cap

4) Installed refurbed AA Valve

5) Checked the spark on all leads

6) Installed new plugs

However, the engine still performs / runs like its on 3 cylinders... Once the injectors were done the engine was running sweet.. Parked the car for 2 weeks, engine back to running like a pig.. All 4 plugs were quite black (even after only running for about 3 miles in total since they were installed), which shows all 4 are getting fuel but running very rich.

If the electrics are good, then it must be fuel? Perhaps the Pump or regulator?.. Anything i can check / test by myself? as my driveway is steep and the car doesnt have the power to get up it to take it to a mechanic

Cheers

Chris

It explains all of the testing procedures and more

Adjust your valves
Check your fuel pressure
Get a Haynes manual
Check timing and spark plug order if you have touched them


You have a lot of reading to do
And a day s wrenching
Let us know what you find




Update…….
Just re read your initial post
I’m betting you have a spark plug wire in the wrong order
Check your firing order
did you pull the distributor... it could be indexed wrong... so check firing order by verifying the motor is on TDC and then look at the rotor under the cap…for that position to be plug wire for cylinder #1 (you can verify TDC and adjust valves at the same time)

It’s almost always the last thing touched by an owner causing the problem

Hi Brant.. Left it overnight and it spluttered into life.. I also thought the leads were on the wrong way round! but an overnights nap seems to have sorted the starting issue.

Next step will be fuel pressure! Will let you know how i get on!
