hi gary

hello

the ICM was changed to correct this code ?

how does it run and drive ?

Customer: replied 1 month ago.
the icm was changed but it still doesnt run and it still throwing the code

now spark out of the coil when cranking over ?

Customer: replied 1 month ago.
not sure how do you do that

if the engine will not start it is missing spark fuel or compression

you need to check for spark when cranking it over

do you have a test light ?

Customer: replied 1 month ago.
nope
Customer: replied 1 month ago.
its cranking like it wants to start but my battery only shows 11 and when i crank it it drops

we have to check for spark and fuel pressure

Customer: replied 1 month ago.
ok how do you do that then

you need a test light and a fuel pressure gauge to test them

or see if it will run on starting fluid sprayed into the throttle body

Customer: replied 1 month ago.
ok give me a few minutes i am gonna try something

ok let me know

again its missing spark or fuel

but with the 1351 code with a new ICM the coil should be changed next

Customer: replied 1 month ago.
changed them both. if the fuel pump went bad would that show a low battery guage?

no

if the engine is cranking over at normal speed the battery gauge reading is not anything to worry about

see if you have spark and see if it will run on starting fluid

Customer: replied 1 month ago.
i dont have any
Customer: replied 1 month ago.
i tested fuel pressure by disconnecting my intake on the fuel filter and cranked it no fuel spilled out
Customer: replied 1 month ago.
where would i spray the starter fluid?

into the throttle body where the air cleaner tube connects to the engine

when cranking it over and NO fuel coming out the fuel pump is usually bad
