Hard restart when warm
Hey guys,
My truck starts fine when cold, but is hard to start when warm. After 15 or 20 minutes it's fine.
Once it does start, the motor revs, then slowly comes back to idle. It also stinks like it's been flooded.
New wires, plugs, cap and rotor.
I'm thinkin' my fuel injectors are leaking?
'90 TBI 318
TIA!

"Once it does start, the motor revs, then slowly comes back to idle." This is normal engine operation.
You might want to check out the Evaporative Emissions System. Hard warm starting and strong fuel smell are both symptoms of this system being faulty. There are 3 solenoids on top of the rear of the passenger side valve cover. The one closest to the firewall controls this system. The solenoid is controlled by the SMEC. A faulty vacuum delay valve on top of the canister will also cause this.
The best thing about having TBI is the fact that you can actually see how well or poorly the injectors are working.
