RE: [DML] Starting Issues



John, 

Reverse the polarity on the fuel pump and see if it seems to run in reverse
ok. If so then jumper the RPM relay to force the pump to run and see if the
3" disk in the air flow meter is hard to push down. If so then you should
have fuel pressure. 

Don't flood by keeping the CSV plugged in as you try to start. Plugs could
be gas fouled / black to the point that it may not run unless you swap them
out. 

Make sure you have a round 9 to 10 volts on the blue / yellow wire on the
left side of the resistor. Then make sure the volts is also on the right
side of the lower part of the resistor going to the + side of the ignition
coil and if not charge the battery over night.

One more thing, unplug the wire going to the fire wall from the ignition
distributor and it should read around 600 ohms. If not the engine won't run.

Gas, fire and compression = starting.

Subject: [DML] Starting Issues

Help needed resolving starting issues:

The car sat for 8 months started every two months or so but now it is very,
very difficult to start and usually won't start at all, when I do get it
running it won't stay running. 
Things I did so far...

1.Put fresh gas in (It was pretty empty)
2.Changed Fuel filter
3.Tried jumping RPM because I could not hear the fuel pump. but it would not
start even with thr RPM relay jumped? The pump does run then. was not before
I guess.  BUT it stops after a 15 secs or so.  Also hard to start even with
starting fluid in the air intake, it does fire though briefly.
Not even after the engine is warm it won't start, does not seem to matter if
it is cold or hot! so I guess that rules out the Fuel Acccumulater

1. Solenoid working 
2. Micro swicth is tripping when it should.
3. Freq. valve buzzing when it should.

Could it be a BAD FUEL PUMP? its only three years old...
Don't want to waste $100 on something I might not need?

Any suggestios?
