Other reasons for flooding?

I dont know why, but when I turn off my car for less than about 20 minutes, it will start up beautifully, and if it sits for more than about 6 hours it will start beautifully again. The thing is, if it sits for more then 20 mins but less then six hours, I get really bad flooding. As in the only way I could get it to start was pull the EGI fuse. So I wired in a fuel pump cutoff, now it starts perfect. But Im still just wondering, why would it flood? BTW, I just recently got all of my injectors serviced, flow tested, leak tested, etc and they are all good. Thats why I dont know whats up with it.

get a compression check.

number 1 reason of flooding is low compression.

Also leaking injectors. Get them cleaned and blueprinted and www.rceng.com or www.cruzinperformance.com but do the compression check first to save yourself some money.

bad ignition spark due to worn plugs, worn spark plug wires, bad engine grounds

Oh yea, compression is good too. I checked that, spark plugs are new. Could be spark wires though. I need some new ones.

could be a hot start problem. related to the air control valve, bac valve, fuel pressure regulator control which cuts vacuum when hot starting, or faulty purge control valve. the list goes on, but it probably has something to do with that if all the common sense stuff checks out fine.

It could also be a hot start problem related to the Hot Start Assist System. See your FSM to check it.

silverrotor- he just got the injectors cleaned and checked for leakage. so that's not the problem. you must have overlooked that part.

Good point. At times I'm quick to answer. On account of the weather In AZ, he may have a problem stemming from the Hot Start System, as Jason Pointed out.

They were cleaned but were the Upper/Lower Grommets replaced aswell?

Yea, all the grommets and pintle things were replaced. I will check out the hot start system and if not that, then the BAC, ACV etc.
Thanks guys.
