I cant figuer this out
 
Thanks guys,

The IAC is working and the car still wont start! Every single part is less than six months old????

The car ran, I adjusted timing and fuel pressure shut it off for the night and it has not started since?

It has fuel it has spark at the plugs

When you turn it over it sounds like it wants to hit for a second and then just cranks

WHAT AM I MISSING?

thx

You need spark (at the right time), fuel, and air.

Make sure the timing isnt off.

How would the timing be that far out when the car was running last time I shut it down?

thx

I will try and put the timing back where it was which was about 25 degrees advanced. that is where the car would run and I knew it wasnt right so I backed it down to about 8 degrees. I am heading out to the shop to put the distributor back in the engine I removed it to inspect the gear.

I have a suspicion the cam timing is off

thank you

25 degrees initial doesnt sound right at all. It should be 8-12 degrees initial, usually 10, itll probly run from -5 up to 15 or more degrees.

Did you remove the cam? Unless your timing chain magically stretched overnight a massive amount it shouldntve moved.

Dizzy is back in and nothing! When I checked the timing with the EST disconnected my timing at 1100 rpm was 21 degrees.

It is a new engine with about two hrs on it. something went south to cause this I am on my second ECM maybe it took a crap again...why


thx

Ok, before you adjusted the timing it was 21deg at 1100 rpm. That would be fine depending on the weights and springs in your dizzy, at 1100rpm your mechanical advance is already kicking in. Your initial advance should be set at 500-800rpm depending on your transmision. As long as your not going over 40deg total with all your timing in or getting detonation. I would suggest pulling out the dizzy and starting over, bring the engine to tdc and set the dizzy in with the rotor pointed to #1 cylinder. Put cap and wires back on and try starting. If it backfires you are 180 out. I like to mark my wires and cap with witeout or paint marker to make removals easy. How are you checking the timing if its not running?

Carb'd or FI? Your profile says 84, but o mention of what engine. If FI, did you disconnect the plug on the firewall?

Yeah,TPI engine. yes the EST was disconnected.
