Moin together! Apologies my clumsy username,but I have not yet out how to change it again I have a problem with my beloved Chevrolet Blazer K5, 5,7TBI from 1988 He starts off super bad.. No matter if cold or warm.bin from my previous TBI’s a different starting behavior.. I have to orgle for ever (ca 6-7 turns, ignition off, then start again and pump with the accelerator as with a carburetor) and then he spits a cloud of unburnt fuel out of the exhaust. Have also had some other small problems but that get under control. New are: petrol filter, fuel cable.Kappe, Kerzen,air filter,temperature sensor at the front of the spider,Rossel valve switch,empty circuit switch, or valve and the EGR valve.The other thing I have tried is also an empty injection system cleaner… Well, the parts won’t break any more in the next time, but it really didn’t help. By the way, I don’t know that there is an electric trigger.
