mystery problem

i have an 95 olds 88 3.8 L motor wont start just replaced all gaskets computer says all clear car says no go feul pressure is 40 psi i have spark feul injectors fire everythings connected even vaccum lines throttle postion sensor is good, iac valve good, pressure regulator good, new plugs and wires what have i missed?

You sure you got your plug wires correct for your firing order? Did you get the vehicle like this or was it running fine and one day you go to crank it and it not crank? Did you do some maintenance or repair work to it then it not crank, if so what did you do to it before the problem started. Which gaskets are new, there are all kinds of different gaskets?

thanks for the reply. i did the wires three times to make sure they where right. i replaced head gasket and up because of a leak that i just found out is common in the intake of this motor. the car ran i parked it, replaced the gaskets, connected everthing and then it wont start. cranks till the battery is dead but wont start. acts like it want to start but does not.

Just incase this is what you should have

Try taking the air cleaner off and spraying in some starter fluid see if it cranks that way.

Thanks ct I tried starter fluid today and it didn't work. I took coils and ignition module in to get tested all good. I'm going to try a new upper intake tomorrow.I am also going to make sure the injectors are truely working and not stuck open.

Fixed the car today it was the stupid spark plugs.
