'88 will not start...

JohnnyBuck · Mar 22, 2010

i have a '88 f150 with a 5.0 that will not start. I have changed plugs, plug wires, dist. cap, and fuel filter,still nothing. I took the Ignition control Mod off and had it tested at Auto Zone ,they said it was bad so I replaced it too.
I really need to know how to the the test codes so I will have an idea where to go from here... also the cross-over tube at the back of the heads has rusted through, but would this keep the engine from starting?

What are the no start symptoms...

Does it turn?

Engine needs 3 things to run, fuel, air and spark...

One of the 3 is not happening...

If the engine turns check to make sure your getting fuel...

Edit: Yes it will run with the rusted out tube, but will run like poorly and you will have a nasty exhaust leak.

Sorry I left out important information, engine does turn,I checked and do have fire at the plug, also getting fuel to the plugs, also brought #1 cyl. to TDC and checked location of rotory button and it is on #1.
Tried a shot of starting fulid still no change.

You hooked up a fuel pressure guage? Whats the reading. You have spark at the plugs? How are you testing?

This odly reminds me of our Sea-Doo, and that did not end up well.

www.fordfuelinjection.com has an area on hoe to pull codes with a paperclip along with a list of codes to decipher what they mean.....verify that you have the plug wires in the correct firing order. should be 1-5-4-2-6-3-7-8

Just got the truck started....Low fuel pressure. still have a slight miss but heading in the right direction . Thanks for all your help

those three things are ....

Fuel spark and COMPRESSION! All must happen at the right time! replacing parts makes as much sense as buying a new truck due to a flat tire! If it aint broke don't fix it. Check for vacuum to the map sensor on the firewall near the AC unit, check compression, a jumped timing chain or bent valves will make it sit still
