So far as I know, there is no engine light, there is no trouble code .The "check engine light bulb can be burned out and does not mean there is no code.
check for code anyway:
use a jumper wire (see red wire above) and connect terminals A and B. Next turn your key on but don't start. Watch your check engine flash the code/s.
EXAMPLE: CODE 12: one long flash and two short flashesCODE 13: one long flash and 3 short flashes.
Note: code 12 is usually the first code you get and just ignore it.Watch the code after code 12, that's what you need.
next, you should do a fuel pressure test ,check that pump pressure is 24-40 psi.
(see diagram for fuel gauge connection)
Start the engine and allow it to idle. The fuel pressure should drop to 28-32 psi (193-221 kPa) due to the lower manifold pressure.if not, check hose that connects the MAP sensor to the engine, make sure it is not loose or there problem with ground or open in the MAP sensor wiring circuit,
I'm sending this diagram to your email.
