Cold start problems...

[TEE]

I'm having a problem with my 94 Silvy crankin' and crankin' when it's cold. It will start after about 10 sceonds when it gets down about freezing.

I've replaced everything including fuel pump and coil but, everything else is new.

Any ideas? I'm stumped

Ignition coil, Cooant temp sensor, Fuel anti-drain back valve.

All replaced. Just had a new pump put in last nite but, the guys didn't replace the fuel lines like I wanted and they look real shabby...especially the fitting right above the tranny where it goes from hard line to soft.

It's getting spark but, no fuel for 10 seconds or so.

You can replace the pump without replacing the anti drain back valve. I would check that first if what you mean by cold....sitting for a while before starting it up. I have the same probelm if the trucks sits for more than a few hours no matter what the outside temp is it has a hard time starting. If you you let the fuel pump run for about 4-5 sec before starting with your foot on the gas a little it helps.

I thought the valve was in the pump ?
