Need Help
Here's the deal i was on the highway and when i went to to get on the off ramp my car shut off ,so i started checking it and it all aimed to the fuel pump,i check the fuel pump and sure it wasn't working,then i get the new fuel pump in and the car tries to start but it won't and since the car has a turbo timer it stays on with the open switch and there is a buzz coming from under the intake manifold, is there a relay or something thats causing my car not to start that would make such a noise??
thx for the help in advance

believe it or not but when my friend was building his drag car (honda lol), he had 2 fuel pumps in..at high rpm and full boost, the engine would choke, almost detonating the engine..he found out later on that one of the pumps was installed in reverse..lol
so i guess thats another possibility..

I would think it was an electrical problem like a bad ground. However if you think it's flooded just take out a spark plug and if it's soaked in gas then you know its flooded. Follow he procedure for fixing a flooded rx7if thats the case.. otherwise get a multi meter and test the voltage at the plugs and check for a ground bolt that might have come loose.

not to be the bearer of bad news but your car has the symptoms a cracked apex seal. mine went the same way (stalled when i got off the highway ramp). then it was really difficult to start and when it did start it would smoke heavily.
do a compression check. good luck.
