3vze No start issues 1990 help!
just bought 1990 toyota 4x4 pickup currently not starting.
to start off i have devoted days to this forum allot of good threads, I've followed everybody advice but I'm stuck.
items replaced in order:
-spark plugs and wires
-fuel pump (started not to start replaced and worked for two days)
parked it to do gasket job....
-value cover gaskets (due to a leak)
-PCV valve
put it back together.... no start...
-EFI main relay
-TPS (after doing hours of searching this forum)
took it to the shop....said it was timing... so i towed it back home.
-AFM +new filter old one was terrible(agin after doing hours of searching this forum)
-dizzy cap and rotor
-timing belt (because shop thought the problem was timing and it needed to be done anyway)
-ignition coil
-fuel pressure regulator
compression 90psi on second cylinder but i thing its due to lack of starting power because I've drained the battery and am running on my emergency battery jumpstarter. fuel pressure 40psi at the rail, I'm getting spark on every cylinder and everytime i pull the spark plugs there covered in gas. i have triple checked the timing and rotor position, dizzy is original could it be that? when ever i go to crank it over the AFM sounds like its going to die (loud clicking).... its within spec though... The tps is maxed out to one side but i get good ohms from the terminals..... please help...
