1998 Chevrolet Blazer Q&A

1998 Chevrolet Blazer Question: starts hard when cold

no problem when started -
Answer 1
Weak fuel pumps are common, you must have at least 55 psi to get the engine to start, 54psi won't open the poppets in the injectors. But with any no-start testing must be done, do you have spark when it won't fire? Are there any codes? -

Thanks. Had fuel pump checked. Low pressure. Needs to be replaced. -
