but can you save the stall, with a fast right foot.
when it stalls do any lamps die in dash or others?
12vdc to the EFI system is the first check.
loss of power, kills EFI dead as a door nail. so .../?????
and the fast foot trick is next , always.
1,2, test 1, test 2 in 3 seconds at stall.

fast foot"
1: easy, (idle air loss, ISC stuck)
2: tad hard, (egr stuck open ,clean it) or flooding.???
3: impossible , lost spark,. or lost fuel pressure.

and rail pressure is dont with a gauge
all other ways are useless, , unless dry.
only 30psi or more is valid. not less.
no injector runs right below 28psi. (read the specs)

my new jeep runs at 60psi. 3.8L
to check rail pressure ,step one is to get the spec.
the FSM cover this.
My FSM shows no V8s, is that a typo.????? sure...
see the wiki and do tell REAL engine.

if you can not tell real engine, i can not tell real specs.
not ever.
USA car, or export???? what COUNTRY ?
again, what car, what country what engine?
cant fix cars , if you can not identify the engine.
here is the list
all tell end if 1996.

on any 1996 , I6, 4.0 engines
1296 means. (not other engines!!!! or cars)
No 5 Volts to MAP Sensor
the 5v line is shorted ,or cut, or the ECU 5vdc power reg, is dead.

with the bad the engine EFI will be hopelessly stuck in limphome.
TPS dead, etc. and will run like craap
and stall.
P1 is a factory code, and you MUST mach code to exact engine,year and maker. or data you read is wrong.
P0 codes are federal codes. and are universal.
P mean powertrain errors.

Your problem is a common one in the early 90's Jeeps. It's called the delayed start, no check engine light problem. Your main computer ECU is in need of repair. There are a lot of posts on this site, regarding this issue and solutions to it. Or, look on Ebay for Jeep ECU repair or for a replacement ECU.

You should never wash your engine. It can really mess with the computer sensors. However since you now have a problem in the rain, I'd change the wires, cap and rotor. (likely old and sensitive to humidity) Also, look at your ignition coil in the dark...if you see any spark or electrical "haze" where the coil wire goes in, change the coil.

The fuel pump is located inside the fuel tank. The fuel tank has to be disconnected and dropped down from the underside of the Jeep, in order to access and change the fuel pump assembly.

Bad neutral safety switch, starter relay, starter fuse or bad ignition switch. You will have to check each of those things to find what's keeping the current from reaching the starter, when you try cranking.

check the neutral safety switch and see if its bad it should be near the shifter linkage on the transmission..see if its broken or out of adjustment..

does the motor crank. if it cranks the starter and altnator are good. now when you turn the key to the start position do you hear the fuel pump? do you know if you have spark at the spark plugs

use a flashlight and try and see where the steering pump fluid is leaking from ~~ it could be a bad hose or loose fitting. identify and replace any bad parts.
