Unhappy What Causes Flooding?



93 Vortec 4.3L CPI ( spider injectors) Vin W

New Plugs, New Distr. Cap. New Rotor Button, New Fuel Lines into The Injector.

I know We have Good Fire,
Cleaned The EGR Valve ( wasnt Dirty ).

What Else determines The fuel/Air Mix ratio?

I have Other Threads That Give More Detailed Info On My engine and its troubles. However Im Good except The Flooding whether its a sensor, its a Electrical/ computer/ Fuel Leak somewhere even Though Holding Good pressure .

Found This On The forums and could a temp sensor actually cause an engine to flood and what about it flooding once The engine is warm?

The air cleaner is right behind the right headlight, Has a filter in it that needs replaced when it gets dirty. It also filters the air for your crankcase.

It's on the driver's side. If you have a 4X4, the cylinder is the oil filter.

Faulty Injectors leaking or spraying too much fuel.

ok Hooked Up pressure Guage and Fuel pressure is Staying at 60 never below 55 and does not leak off, This while going down the road and while idling in park and while engaged in gear idling.

I left The guage hooked up laid it against windshield using wiper to keep it in place plus the hose is stiff and that helps, Drove to the garage and hoping they can get to it by Tuesday next week.

It had the smell of stale gas and white looking exhaust when it idled for a while and was given gas and smelled bad of gas fumes all the way to The garage Bout 10 Miles.

While I was already prepared to buy new cpi set with new regulator and poppit nozzels, The steady fuel pressure seems to dictate the issue lies elswhere.
