no, it warms by compression heating.
Remove the cowling from the top of the engine. They are under there.
are there freexe out pluges on rear of block on a 2.3 engine ford ranger
check ur pluges and wires but also check ur starter
the last time i changed the spark pluges in my 86 subaru gl wagon, i took the engine out. seriously, it needed a clutch at the time.
=because your in water=
If you didn't replace one spark plug wire at a time you may have mixed up the firing order.
(1) disconect battery ( 2) under hood on passenger side remove 2 10mm boltes (3) pull ecm out disconnect 4 wire pluges
Without an engine size we guess but if you can't see them then they're under the center plastic cover of the engine. Cover will have coils,wire boots, module & plugs under it.
try checking your 02 sensors
Check valve timing and for correct valve operation.
