Engine wont start when wet - 2000 GMC Jimmy

i think you should do minor engine service

Depends on how wet it got. There is high voltage present at the coils for the spark plugs, water shorts those out. If water got into the cylinders then the sparkplugs wont spark either.

check your fuel pressure regulator,pull the vacuum line off it is wet with fuel,replace it,then put vacuum pump on regulator side see if it hold at least 15 psi steady,if it start loosing vacuum ,change it,

First check the air filter to make sure you didn't suck water into the filter.

Open hood a let dry,never spray the engine down,use a wet rag and wipe.Get a dry rag and wipe water up,

How long has it been since the snow filled the bay? Has the snow been cleared away and is the bay now dry? If not, there's probably some connection somewhere that is wet and therefore not making a good connection. The bay will probably need to be thoroughly dried before the engine will readily start.

Does the engine have a distributor on it ??? if so see if thats wet, you will need to clean and dry that out.

if its fuel injected take a hair dryer and aim it at the injector rail where the injectors stick into the engine and dry that a bit..

you may have got the coils wet on engine. check to see if they are wet!! or any electrical part.

gets wet on top or bottom of engine, on top water might of got into the spark ignition system, on bottom, could of got water into a sensor until it dries out, ford are **** wits and want ur money, id take it back and say since that didnt work fix it for free ya ****.

first thing to do is after trying to start engine, remove a plug, see if its wet or dry. if dry, no fuel getting there, if wet, ignition problem, then we willl take it from there
