Non-start issue

After sitting for an extended period of time... 18 months... I have finally completed all of the maintenance items that I could tackle this time around.

This included the timing and balance belts as well as a water pump, new rollers, distributor cap, rotor, new plugs and wires.

I have also replaced the engine bay fuel lines (all three elements), had the injectors serviced, installed a new oil and air filter, cleaned the intake manifold, replaced the AOS and it's seals, rerouted the hoses back to a more stock configuration, though still with the venturi delete.

I have also replaced the coolant and the hoses.

So after fully charging the battery, I began the process of waking her back up, with the anticipation of checking for leaks, and bleeding the cooling system.

She cranked, and seemed like she wanted to fire, but stumbled and coughed out. Never making even a lumpy idle last.

I drained all of the suspect fuel via siphon (though I had added stabil one month into her rehab), and replaced with fresh gas. Same result.


I know it's very difficult to diagnose remotely... but am I missing something?
All of the wires are plugged in, All of the injectors appear seated, there are no fuel leaks. The most (including under the manifold) vacuum lines have been converted to silicon, I have replaced any other cracked hoses.

The car ran before I began disassembly... even passing smog. All of the gauges appear to be working... I have oil pressure, and volts.

Have you switched the connections on your Speed/Reference sensors and tried?

After that, look for the Holy Trinity: Fuel, Spark and Timing

Thanks Mr. Jones,

I didn't touch those, so I am leaving those sensors out of the equation.

I will attempt the fuel pump jumper first.
I did rotate the engine by hand after this and made sure that the marks line up... so far so good.

I don't want to keep cranking an engine that won't fire, but I want to make sure I tried enough to pull the new gas in. I am thinking making sure the pump hasn't perished (or the relays) would be a good step to start with.

Thanks again

Are your plug wires all orientated correctly?
Check your fuel pressure also.

Thanks Jack as well,

They are (neatly labeled and solidly clicked into place).

I think the issue will be with the timing, I have a new woodruff key on the way.

I'll update as I trouble shoot.

The fuel injectors are bad about sticking might have to take out and flush them with a cleaner.
good luck . la
