4.3L Crate Motor Wont Start

1998 Chevy s10 new crate motor will turn over want start.

Answer: There could be many many reason why a new crate motor will not start. Most common is that the installer forgot to plug something in, broke a sensor, broke a wiring harness or connector, blew one or more fuses or fusible links, etc. We would need much more information than just – it wont start.

Does the engine have spark while cranking? Does the fuel pump run and is the fuel pressure correct? Does the engine have fuel injector pulse signal? Is the check engine light on with the key in the ON position like it should be? Are there any codes stored in the computer? Is the theft security warning light on the dash?

As you can see, there are a number of things to check. Send us more information and maybe we can help, thanks.
