The Haynes Fuel Injection Diagnostic Manual

Haynes has put together a great manual on Bosch Jetronic, K-Jetronic, CIS-E, and Motoronic systems - that's 3/4 of the book. The rest is the most basic of basics about sensors and testing, same type of stuff found in in the first chapter of any service manual. The manual is detailed and well written, but it needs to be said that the focus is on Bosch's distributor-type fuel systems. It is worthless with respect to Japanese and American EFI systems. If you are looking for a great reference for Jetronic, this is a thorough and inexpensive manual that is more maintenance-specific than the official Bosch book, which is hard to find. If you want to learn about fuel injection principles, try "How to Tune and Modify Engine Management Systems" by Jeff Hartman. Were I after specific information on Bosch systems, I would rate this 4-1/2 stars. It is great reading for that particular system, but lacks part numbers or model/year reference. Since the title deceives the buyer into thinking this is a book about all types of fuel injection offered in the years stated, I would take away another star. Given that it is a well written book despite its narrow scope, I will rate 4 stars with the caveat that the potential buyer understands that it is focused on the Bosch systems found in Volkswagen, Audi, Volvo, Mercedes, and a few others that used CIS extensively during the 80's-90's.

The data you need to attack those fuel-injection system problems. How to obtain and read those cryptic ECU codes from most car models, using comprehensive code tables with meanings. The first half of the book gives a good introduction to FI systems, the tools required, and symptoms to look for. Lots of photos and diagrams. Excellent value for money.

Very Informative Book. The information is not in detailed I would liked, or the information is to brief. Not enough troubleshooting Guideline. But You can get a decent amount of some informative and repair direction from this book. WORTHY BUY BOOK!! CAN'T BEAT THE PRICE!! USEFULL!!
