No Start

I picked up an 89 to steel some parts and sell off the rest but I wanted to get the truck running(worth a bit more running). It has sat for about 2-3 years.

I had to put batteries, starter and starter solenoid in it.

Cranks over strong.

I am giving it wiffs of ether but it doesnt even want to fart. Nothing, just turns over.


Has banks turbo kit if that makes any difference

Suggestions?

I just plugged the block heater in to let it sit for an hour or two and see if that makes any difference

Get a cheap electric fuel pump and by pass the mechanical fuel pump. That should rule out any possibility of it not pushing fuel. Or just replace the mechanical fuel pump it’s only like 40$ your choice. Sound like that’s the only thing you haven’t checked. All though it is kind of strange that the ether didn’t bump it even a tad.

I was just going to gravity feed the IP from a washer jug before I spend any more money

Their is a schrader valve on the fuel filter hold it open crank see if their is fuel pumping. Number two check their is power going to the fuel shut off on the ip. Three crack some injectors hold the metering valve wide open and crank it over till you start seeing fuel. Tighten injectors back down. Do 3 or 4 of em. Plugging it in will help loads to help start. And you pull the fuel filter off and see if it full or partially full and filling it up will help with priming.

One thing not to overlook - FSS on the injection pump. Key on, disconnect and reconnect the terminal, you should hear it click on and off.

But it did not try to start on starting fluid. Would a bad FSS do that?

Kind hard to hear anything click over the GP relay but I will check it

No, ether alone should at least make it fart, but I am not getting fuel so that could be another issue

If it's not hitting off the ether then either you have a rats nest in the intake or no compression.

GP relay should only make noise when it's clicking on/off. If you disconnect / reconnect the FSS connector while the key is in RUN, the GP relay shouldn't be making any noise at that point. If you have one of those GP relays that screeches/whistles the whole time it's energized, stick a fork in it, it's done. 'Course, you can always disconnect the GP relay for the FSS test.

No nest. And it turns over way too hard with new batteries and starter to not have compression'

What would pushing on the pedal do?

5 seconds? That would surly lock up the engine

thing about ether is you want the engine turning before you spray. I have heard it is possible to make the engine spin in reverse if the cylinders are full of ether before you turn it over. It may have been the old 2 strokes that had the problem.

Well, I rigged up a test fuel can and changed the fuel filter.

getting fuel thru the filter head but nothing out of IP. Looks like Injection Pump is bad(yes I have power to the fuel shut off)
