Hi there,
i,m a first time chevy owner the van is
4.3L
petrol / converted to gas aswell
astro van
left hand drive
1993
80,000 miles

I bought this van about 3 months ago and decided to get the gas conversion done as recommended for fuel consumption purposes.

The van also needed the plug and leads doing as it was misfiring alot.

I have now had the spark plug changed, dizi cap, leads, r arm and afterwards the van was driving like a dream.
Then......

went out yesterday stopped at cash and carry then when i tried to start again it just kept turning over and over like a fuel problem.
recovery came out but they didnt know very much about the make and the gas conver so all they were able to do was take me and the van home. Yes alot of help lol

Know im at a loose end.
I live in the uk so not very many know much about these models and so dont really want to touch them. And even less know much about gas conversions so i dont nkow what to do with it or who to take it too.

Any help would be much appreciated
thanks in advance

is it both gasoling and gas? or is it just a gas conversion strait up?

colin mctaggart

its both petrol and lpg ( gas)

2wd-K5

and it wont run on either fuel? if it doesnt run on either fuel check the switch they put in for choosing each fuel, and check out the connections, see if they are still attatched

ok, ive worked out that i can start it on gas doing an little fiddling wit the switch ( the one that switches it over form gas to petrol)

it starts on gas / lpg and drives so it looks like the fuel pump has gone. No nooise coming from the pump when i turn the key.

where is the recommended places to get a fuel pump ( remembering im in uk) is there any rules to follow when purchasing one , good makes , bad ones etc etc

many thanks colin

a GM dealership isa good place to start, maybe someone knows what fuel pump will work for you

Hi Colin McTaggert,

Welcome to the Chevy Forums.

Are you getting a solid spark to all your plugs?

Some time when you get a chance, take the dizi cap and rotor and have a look at the ECM. If the dielectric grease on the plate on the bottom of the ECM has dried up, it probably burnt out the ECM. Most large parts stores carry new ones cheap.
