fuel injectors

[go fast]

hi there everyone.. If i sprayed engine degreaser around the fuel injectors where they sit in the manifold would it affect them in anyway i need to get the motor clean as much as possible,i am going to show it off at a car show any thoughts would be great?

if you do that make sure you run the engine after you have washed it to remove any water traps

And make sure the degreaser you use is solvent based - if you use a caustic based degreaser (like 5 star) you will etch any alloy plus cause paint to fade. The stuff from SuperCheap in the spray cans ($2.09) is solvent based. Don't use a gerny either as it has too much pressure, just a garden hose is OK. Also do not degrease a hot or warm engine as it can leave stains behind. Finally don't leave it on for more than a few seconds.

cool man,thanks for the reply,hope it comes up alot cleaner than it is at the moment,cheers

I believe the main reason for doing the engine while cold is that washing a warm/hot engine can cause condensation to form in electrical components/plugs/switches, etc.

i have brought some degreaser and going to start cleaning motor,just need to know,should i cover the coil and distributor to be safe or should it be ok as the water runs off the manifold might go over the coil and the distributor, P.S just checking

I'd personally cover both - you can clean them separately later with a small brush.

Is your only issue with cranking over? If so then it sounds like a starter motor issue.

[immortality]

could be ignition. could be the battery or the connections. could also be a fuel pressure issue

You could have got new injectors for that price.I just got brand new "cheapies" from ebay.$160 a set they cost.New bosch VT type injectors are around $300 a set on ebay.There are also fully cleaned rebuilt bosch injectors on there for $99 a set.If youve replaced the fuel pump and the fuel filter,and the fuel pressure regulator is working fine,then the problem probably lies elsewhere.Unless the new fuel pump is faulty.
