I've got a 93 2.4 Diesel Surf. Eversince replacing its old n damaged fuel pump...this red light on the dashboard next to the turbo light has been on!!...and it never goes off!!....whenever you start the engine in the morning there is a lot of smoke and you can feel thats its not idle (the gear shaking!)...what could possibly wrong?? Any useful suggestions would be a godsend!! and highly appreciated!!
