I’ve gotten GREAT info here about my ranger, so figured I’d try again. Just got handed down a 1987 F150 L6 300, 4 speed, Extended Cab Long bed.

At first I was not getting spark and found distributor not all the way in the block (rotor not spinning). Now distributor is flush with the block, rotor spinning and timing was reset. Spark plug #1 was pulled until compression stroke was felt and crankshaft pulley notch was set at 0. Now I have spark.

Started the truck with starting fluid and it ran for about a minute. I shut it off and tried to restart, again with starting fluid but this time ran for only 5 seconds. Called it a night and jumped back into it this morning.

This morning starter solenoid welded itself and would not stop cranking, battery terminals were pulled and solenoid from the ranger was installed. All is working again.. except it won’t start, even with starting fluid.

I pulled distributor and I reset the timing again, even tried a new ignition module but no luck. High pressure fuel pump in the rail under drivers seat is running. Any help would be appreciated, thanks!

Pull the SPOUT and see if it runs.

Check your grounds.

Check fuel pressure. The 300 needs 65psi IIRC.

Truck will not run with spout pulled. Grounds appear fine, but may be corroded inside. I have 2 inline fuel filters, paper element before pump and canister after the pump. I will check fuel pressure and report back. Thanks!!

Sounds l like it is a fuel issue. At least partially.

The 87 F-150 300-6 should be pretty familiar to you. It's mostly the same as your 91 Ranger 2.3, just bigger parts.

Fuel pressure is 10psi KOEO and while cranking. I disconnected the canister filter and turned the key on, no fuel came out just air through the pump.

This is the first inline filter I have, before the pump. Does the bottom plastic come off to access the paper element? Or does the entire unit have to be replace or bypassed?

They unscrew off the bottom kinda like an oil filter.

But its a 50/50 if theres really a filter there.

Pull the line off running into it. Turn the key on. You should get fuel pumping out. Sounds like the low pressure intank pump shit out.

Or if you got dual tanks try switching tanks. I believe in 87 they still ran the vacuum switcher. It could also be the culprit.

Will it reach up towards the brake master? Also there might be a proportioning (not the right name but I'm brain dead right now) valve in that area.
